What an interesting and beautiful project.
I did feel like this line was kind of a throwaway though:
"People that have difficulty reading are often capable of thinking in ways that others aren't," Barclay explains.
Perhaps this is true and with more explanation, could have been revelatory for some. I focus on this line, because as part of a sales pitch, this was one line that made me doubt the creator.
Without sounding like I ascribe to the "snowflake" mentality (hopefully), we are all capable in thinking from unique perspectives. If we were not, then what value would the exchange of ideas have?
Also, not to get down on the dude, or his project but there are still many places in the world where dyslexia is not recognized as a real condition and where it is treated as stupidity or obstinacy. I think it's interesting to try to illustrate how dyslexia can affect the experience of reading, but I'm not really surprised that very little effort was made to help people understand what it's like to struggle with reading. Honestly, from what I've observed, a lot of people are not great at reading. It's a skill and like all skills, it can degrade over time if one doesn't practice.
Furthermore, people have weird ways of evaluating and valuing reading. Reading for meaning is good, unless it's done slowly. Reading quickly is good, but only if retention is high. Inference is desirable, but only the interpretations that fall within the evaluator's definition of correct. Small wonder that other creatures rely on chemical impulses to make their way through life.
